Vibration test of the CHEOPS satellite

The CHEOPS satellite is mounted on a longitudinal shaker that forces it to vibrate at different frequencies. At the beginning of the test, performed at RUAG Space in Zurich, Switzerland, low-frequency sine-wave vibrations of 5 Hz are applied. As the test progresses, a sweep, using sine waves of increasing frequency, is performed up to the maximum of 100 Hz.

CHEOPS Children's Drawings

Together with the CHEOPS space telescope more than 2700 miniaturized children's drawings will fly into space. The video shows how physicist Guido Bucher produced the plaques with the drawings at Berner Fachhochschule in Burgdorf.

CHEOPS satellite integration

Integration of ESA's CHEOPS science instrument (top) with the spacecraft platform (bottom) in the cleanroom at Airbus Defence and Space in Madrid, Spain.
The science instrument, which includes among other elements the telescope and detector, was built and tested at the University of Bern, Switzerland. It was shipped to Spain in April to be integrated with the spacecraft platform for further tests and launch preparations. Once in orbit, CHEOPS will observe transits of known exoplanets around bright stars to characterise these planetary systems.

Preparing CHEOPS

The space telescope CHEOPS (CHaracterising ExOPlanet Satellite) instrument has left a clean room in Switzerland, where it was assembled and tested, and is now in Madrid for further launch preparations. The telescope will study hundreds of known exoplanets using the transit method - measuring the dip in light as a planet transits its parent star.
CHEOPS will herald a new era of discovery. Its precision measurements will give more detailed information about a planet’s structure, atmosphere and surface temperature. It was built at the University of Bern and the mission is a partnership between ESA and Switzerland with additional contributions from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden, and the United Kingdom.
Integration and testing of the CHEOPS spacecraft is ongoing and the project is on track to reach flight readiness by the end of 2018.

Cheops: how to build a planet-watcher model

Print out and build a paper model of Cheops, the CHaracterising ExOPlanet Satellite, a space science mission to study known exoplanets orbiting bright, nearby stars.
Cheops will measure accurate sizes of Earth- to Neptune-sized planets. By combining this information with existing mass measurements, it will be possible to establish the bulk density and to put constraints on the composition of these planets. It is a Small-class mission in ESA’s Science programme in partnership with Switzerland, with important contributions from other ESA member states.
Cheops paper model: http://sci.esa.int/jump.cfm?oid=59851
Building the model requires scissors and glue. Remember to take into account ample time to cut out all the pieces.

CHEOPS – assembly at Airbus Defence and Space

This film clip, produced by platform contractor, Airbus Defence and Space ( EADS CASA Espacio S.L, Spain), is a
compilation of CHEOPS AIV and test activities in the six month period starting in Summer 2015, undertaken at facilities
in Spain, Switzerland and the Netherlands.

Inspecting the first CHEOPS hardware - At the University of Bern, the first hardware for the CHEOPS space telescope was delivered and inspected. This included the support structure for the Baffle and Cover Assembly (BCA). In June, Christopher Broeg and Eduardo Hernández León had a close look at the content of the box from Airbus Defence and Space (ADS) – Spain.

Testing the CHEOPS space telescope

Testing CHEOPS at the University of Bern - The space telescope dedicated to characterize exoplanets is taking shape. A camera installed in the clean room in Bern shows how the CHEOPS team prepares the structural and thermal model for tests in the vacuum chamber.

How to participate in the Cheops drawing competition

Do you want to send your art into space on the new Cheops satellite? Join the Cheops drawing competition, and be in with the chance that your drawing will be miniaturised and engraved on two plaques that will be put on the satellite. This animation shows you how to participate.
1. You need to be a child between the ages of 8 and 14, from any of ESA’s Member States or cooperating states.
2. Download and print out a standard drawing sheet (provided here: http://www.esa.int/CheopsCompetition )
3. You can be as creative as you like, as long as you let yourself be inspired by the theme of space and/or by the Cheops space telescope.
4. Make your drawing in black and white, using a black pencil or felt-tip pen.
5. Fill in your personal details and send your drawing via letter to either your local Cheops mission partner institution, if there is one in your home country, or to ESA directly.
6. Entries will be accepted until 31 October 2015.
Up to 3000 drawings will be shrunk down by a factor of about 1000 and engraved on the metal plaques that will fly into space on Cheops.
Find more information and the rules, terms and conditions, here: http://www.esa.int/CheopsCompetition

The power of Dark Energy may be increasing as the universe ages. Subtle clues are emerging that the accepted model for the nature of dark energy and dark matter may not be all that. We saw the first such clue recently in our recent episode on the Crisis in Cosmology. Today we’re doing a Space Time Journal Club to reveal another clue. We’re looking at a new paper in Nature Astronomy, “Cosmological constraints from the Hubble diagram of quasars at high redshifts” by Risaliti and Lusso. It hints that the cosmological constant may not be so constant after all. In fact it may be increasing. If this is true, then our prediction for the future of our universe looks VERY different, and may involve the entire universe tearing itself to shreds at the subatomic level in the Big Rip.
On this edition of Space Time Journal Club we look at:
Risaliti & Lusso (2019) "Cosmological Constraints from the Hubble Diagram of Quasars at High Redshifts"

NASA ScienceCasts: A Super Start to 2019

2019 is an excellent year to look to the sky and enjoy the spectacular view of Earth’s nearest neighbor, the Moon.

Do black holes contain dark matter?

Black holes grow by accreting matter under gravity; so surely they should be able to accrete dark matter? So then is there loads of dark matter trapped inside black holes?
Turns out it's a bit more complicated than that because of what we know of how dark matter behaves - which isn't a lot! - but it's enough.
This was a really fun speculative question to think about, especially because it ties in with my PhD thesis too. Let me know if you want me to do a video describing my thesis down in the comments.
Both my lapel microphones ran out of battery this week. Thankfully one of them didn't need a battery to use with a smartphone, so the sound was recorded that way. It's not brilliant I know, but it'll do. My research schedule this week stopped me from delaying filming until I could get a battery. The sound suffered so science wouldn't.

Space Weather News | A Filament Sandwiched by Sunspots 03.20.2019

UPDATE: Part of the filament I talk about did erupt after I posted this video! We could have a part-Earth directed solar storm coming by the end of this week! Check my twitter feed for the latest on arrival time!
Original Video Description:
This week we are coming down from a solar storm from some fast solar wind, but that doesn't mean the fun is over! We have two fast-growing sunspots on the Earth-facing Sun and they are sandwiching a filament that is growing more unstable by the day. If this filament erupts within the next day or so, we could have an Earth-directed solar storm! We are keeping a close watch on this to be sure. Also, one of the new sunspots may be showing signs of an influence of solar cycle 25. Just like the previous rogue sunspot we saw a few weeks ago, this new region has a dominant magnetic signature that runs north-south instead of east-west. Its too early to tell what the final polarity of this region will be, but if it continues this way, it will be yet another signal that solar cycle 25 is closer than we think! Learn the details of this filament sandwich, get the scoop on the two new sunspots that may cause its launch, and see what else our Sun has in store for us this week!
